With load.provider = "LoadImport", EOSdash requests Akkudoktor-only statistics and returns an error instead of rendering any prediction charts when the API correctly responds with 404.
Fetch only keys advertised by /v1/prediction/keys, tolerate individual 404s if availability changes, and render the load mean/stddev lines only when their series exist. Charts without their required series are skipped; empty/all-null responses produce a no-data message instead of invalid axes or concatenation errors. Other HTTP failures remain visible.
Regression coverage uses real Bokeh plotting for LoadImport, LoadAkkudoktor/Adjusted, independently available statistics, missing/empty series, and non-404 errors. The existing timezone/DST regression remains covered.
